[Class 18.] A powder blower comprises a container with flexible side walls and a discharge outlet 24 in the top thereof and movable means within the container to hold the body of powder in proximity to the discharge outlet. The movable means comprises a partition 34 wit h a double-flanged edge of flexible material, e.g. rubber, the sliding movement of the partition in the container being retarded by friction. A thin rubber tube 36 constituting a lower compartment 33 is cemented to the bottom of the container and its upper end wall is cemented to the partition 34, or the partition may be omitted and its place taken by the end wall of the tube. The outlet 24 is provided with a valve to prevent the inward flow of air, this valve comprising an inverted cone held down by a resilient string ; and the outlet can be covered over by an enlarged part of a rubber strip 16 whose ends are cemented to the container, this closure being pulled aside by means of projecting leaves on a disc secured to the centre of the strip 16. Vertical ribs are moulded on the sides of the container for stiffening purposes, and when these walls are squeezed, air and powder are forced out through the outlet 24 and the air in the' lower compartment 33 is compressed, thereby tending to force the partition 34 upwards. On releasing the pressure on the side walls of the container, air is drawn into the powder compartment through an inlet valve 27, and a small amount is drawn into the compartment 33 through a valve 41. The valve 41 is connected to a rubber diaphragm situated at the bottom of an annular wall provided with lateral air passages. To lower the partition 34, the valve 41 is pushed upwards by means of the rubber diaphragm to allow the air in the compartment 33 to escape. The container is preferably of rubber and cylindrical in shape, and the outlet 24 is located in a cap screwed on to the container. The device may be variously coloured.

Patent GB-516173-A (GB)
Title: Improvements in or relating to counter mechanisms
IPC: G06M1/28
Filed: 1938-03-22
Abstract: 516,173. Counting - apparatus. VEEDERROOT, Inc. March 22, 1938, No. 8786. Convention date, March 22, 1937. (Class 106 (i)] A counter mechanism comprises a number of operatively connected number wheels associated with a driving mechanism and with a resetting mechanism having a resetting shaft and controlling mechanism adapted positively to operate and maintain a brake in braking connection with the driving mechanism during the resetting operation. The counter is of the kind, described in Specification 458,178, and comprises cost counters 1 and quantity counters 2 driven by trains of gearing from shafts 10 and 11 respectively. The latter are driven by bevel gears 8 and 9 acting through clutches 12. The counters are zeroised by notation of a shaft 21 which drives a reset shaft 20 for each counter as shown in Fig. 15. The shafts 20 are provided with usual grooves 27 co - operating with usual pawls 28 on each number wheel. The gear wheels 16a, 16c of the driving trains of the left hand cost and quality counters are provided with blocks 41 cooperating with a stop arm 42 loosely mounted on shaft 21 and the clutches 12 are provided with brakes 47. The stop arm 42 and brakes 47 are operated by mechanism driven by the shaft 21 and restored to their original position by spring action. This mechanism comprises a cam 55 having a notch 56 co-operating with a pin 72 carried on a plate cam 73 pivoted on the shaft 10. This cam 73, through a pin 86 and arms 87 and 88, operates a member 91 which actuates the brakes 47. The braking action occurs after a very slight motion of shaft 21 and therefore at the beginning of the resetting operation. A non- return pawl 113 is associated with the cam 55 and a ratchet 58 and prevents fraudulent reversal of motion of the shaft 21 during resetting. The stop arm 42 is operated by a pin 130 engaging with a link 132 which is pivoted to the end 114 of the non-return pawl 113. The latter is moved by a pin 127 on cam 73 under the control of a latch 118 also controlled by cam 73. The arrangement permits reverse rotation of the shaft 21 under the action of the restoring spring 75 of cam 73 at the end of the resetting operation. This ensures the picking up of counter wheels in the "9" position. Specification 425,473 is referred to.
Patent GB-1255992-A (GB)
Title: Data processing apparatus
IPC: G06F9/38
Filed: 1969-02-19
Abstract: 1,255,992. Data processing; shift registers. INTERNATIONAL BUSINESS MACHINES CORP. 19 Feb., 1969 [29 Feb., 1968], No. 8968/69. Headings G4A and G4C. In stored-programme-controlled data processing apparatus, a controller includes means to register both the address of each branch instruction which causes branching and the address of the instruction to which branching occurs, and to monitor the addresses of the instructions accessed from store, being responsive to recognition of the address of a branch instruction which is registered to address the store with the associated address to which branching previously occurred. A prefetch argument register, which addresses memory to prefetch instructions into a buffer, is normally incremented but may be modified as follows. Nine first registers are provided, each with a validity bit and an associated second register. The prefetch argument register is compared in turn with each of the first registers. If one gives equality, and its validity bit is set, the contents of its associated second register are gated into the prefetch argument register. However, equality with the ninth first register, if its validity bit is set, will also inhibit any gating from any of the second registers other than the ninth (which is an "effective branch address" register). Before or after one or more prefetch operations have taken place, a "load" operation may be performed as follows. A load argument register (which usually will be the ninth of the first registers) is compared with the first eight of the first registers in turn and the validity bits of these registers are concurrently tested. If the validity bit is set and there is equality, or if the validity bit is reset, the contents of each of the later first registers (including the ninth) are shifted up (i.e. earlier) by one register, together with the contents of the corresponding second registers and the validity bits, and the operation of the next sentence is inhibited. In the "load" operation, if the validity bit of the ninth of the first registers is set, shift up occurs at all levels i.e. ninth to eighth, eighth to seventh ... second to first, with respect to all the first registers, second registers and validity bits. The validity bit of the ninth register is reset on an unsuccessful branch. If a branch instruction condition is successfully resolved in the instruction execution area of the system, the memory address from which it was fetched is entered in the ninth of the first registers and the branch-to-address is stored in the corresponding second register, then if the address occurs again e.g. in a subsequent iteration of a programme loop, a successful comparison will occur. The apparatus may be used to vary the prefetch sequence in accordance with a more advanced knowledge of the operations needed to solve a given problem and the availability of portions of the instruction execution unit.

Title: Soft resilient linings for dentures
IPC: A61C13/23
Filed: 1942-07-03
Abstract: 558,470. Linings for dentures. KINNEAR, R. A., DAVISON, J. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 3, 1942, No. 9196. [Class 81 (ii)] Dentures are provided during fabrication, or subsequent to fabrication, with a resilient lining comprising a plasticised polymer or interpolymer of vinyl chloride containing between 20 and 70 per cent of a plasticiser which is preferably dibutyl phthalate. The plasticised polymer or interpolymer of vinyl chloride may be applied as a film or by deposition on the denture from a solution or aquaeous emulsion, but, in the preferred process, a plasticised polyvinyl chloride paste is used. Preferred interpolymers are obtained from organic compounds which contain the group CH<SP>2</SP>=C<, e.g. vinyl acetate, methacrylic esters and styrene, such organic compound constituting not more than 20 per cent by weight of the polyerisable mixture. In an example, a waxed-up model of a full denture was invested to the gum margin in white plaster in a flask and the wax removed by boiling water. The plaster model on which the wax denture was built was then coated with five layers of tin 9.003 inches thick. The other half of the plaster mould was coated with 1 part of water glass in 1 part of water, and allowed to dry. The mould was then packed with a monomer/polymer dough prepared from "Kallodent" 222 (Registered Trade Mark), the two halves of the flask being separated by sheets of "Cellophane" (Registered Trade Mark) during trial closures. When the mould was completely filled with dough, the excess was cut away, the cellophane and tin foil removed and the plaster model coated with sodium silicate solution and allowed to dry. A thick paste comprising 60 parts of polyvinyl chloride and 40 parts of dibutyl phthalate was then spread on the surface of the dough, the flask partially closed, clamped and pressed until fully closed. The clamped flask was then immersed in water at 30‹C. brought to boiling temperature in 20 minutes and left therein for 40 minutes. After cooling slowly to room temperature, the denture was deflasked and the lining trimmed with a sharp blade. In a further example, the lining was applied as a self-sustaining film of 45:55 polyvinyl chloride/dibutyl phthalate composition to the Kallodent dough in the flask prior to polymerisation. Specification 500,298, [Group IV], is referred to.
